I should add that we have tested the persistence option with PostgreSQL
with the above liveCD and it works nicely: a) boot the liveCD b) plug in
any USB memory key (or any other USB storage device, like an external
hard drive - I've been using the tiny Seagate 2.5GB drives and they work
really well)c) copy a single file to the root directory of the USB
device - no need to reformat it or create a partition on it d) reboot
the liveCD and choose persistence mode -> PostgreSQL is now mounted from
the USB drive, and all data is staved there. It seems fairly robust,
even when you pull the USB drive out without shutting down. I wouldn't
recommend it for routine production use but it is great as a demo or for
a trial system.
